  • Heat amp; Temperature|Thermal Properties of Matter

    This energy which is transferred from one body to another without any Mechanical Work involved is known as HEAT. Heat is a form of energy and heat transfer from one body to another takes place by virtue of temperature difference only. Also heat transfer takes place from the body at higher temperature to a body at a lower temperature.
